Nasal NK/T lymphoma
Before 2000, NK/T lymphomas were not a clearly-defined entity and were lumped together with other lymphomas of the nasal cavity.
NK cell has worse prognosis than B or T cell lymphoma.
Nasal lymphomas in Western populations have a better prognosis than in Asian countries. This may be due to a higher proportion of NK lymphomas or EBV-associated tumors in Asia.

- 113 pts.
RT is recommended as the primary treatment. Consolidative CT should be considered for pts with adverse risk factors or Stage IIE disease.
- Japan, JCOG0211 - phase I/II
- 33 pts total; 23 pts on phase II. Stage IE-IIE. Concurrent chemo/RT with 50 Gy and DeVIC (dexamethasone, etoposide, ifosfamide, carboplatin) x 3 courses.

- 27 pts treated to recommended dose from phase I. Median f/u 32 months. 2-yr OS 78%. (Historical control of RT alone: 45%) 77% with CR, 1 pt with PR.
- Conclusion: chemo/RT is safe and effective
- Korea - phase II
- 30 pts. Stage IE-IIE. Concurrent chemo/RT with median 40 Gy and weekly cisplatin. Followed by 3 cycles of VIPD (etoposide, ifosfamide, cisplatin, dexamethasone).

- Response rate to cisplatin+RT: 100% (73% CR, 27% PR). Overall CR rate (after VIPD): 80%.
- 3-yr PFS 85%, OS 86%.
- Conclusion: recommend concurrent chemo/RT

- Retrospective. 100 pts. Various types (many were T-cell). RT alone or chemo->RT.

- Note: per the Working Formulation, most were diffuse large cell type. Immunophenotype was not available for most patients.
- Retrospective. 70 pts. Western population.
- Improved FFP in those treated with CMT vs RT alone.

- All pts are NK/T (CD56+). 79 pts (61 chemo+RT, 18 RT alone). CR in 68.4%. Of those, 44% relapsed. 5-yr DFS 35.5%, OS 37.9%. No difference between those treated with RT alone vs combined modality.

- 102 pts. RT alone to median dose of 45 Gy. 72% CR, but most of those experienced relapse, and 47% of all pts had local failure.
- Conclusion: high local failure rate with RT alone. Plateau in dose response curve around 54 Gy.

- Retrospective. 105 pts. Stage IE and IIE. Pts received RT alone or combined modality. Initial RT resulted in CR of 83% vs CR of 20% for initial chemotherapy. OS and PFS were similar for RT alone and CMT.
- Conclusion: recommend RT as primary therapy. Addition of CT does not lead to improved survival.
Doses >50 Gy are recommended.
